安樂集 1.19

1.19

答曰：「《涅槃經》云：『西方去此四十二恒河沙佛土，有世界名曰無勝，彼土所有莊嚴亦如西方極樂世界，等無有異。我於彼土出現於世，為化眾生故，來在此娑婆國土。但非我出此土，一切如來亦復如是。』即其證也。」

The answer is: The Nirvāṇa-sūtra says: 'To the west, past as many buddha-lands as forty-two Ganges sands, there is a world named Invincible (Aparājita). All the adornments of that land are also like the western world of Sukhāvatī, equal and no different. I appeared in the world in that land, and for the sake of transforming sentient beings, came here to this Sahā world. It is not only I who appeared from that land; all Tathāgatas are also like this.' This is the proof.
